PURPOSE:To facilitate mode control of a laser light radiated from a semiconductor laser. CONSTITUTION:A laser light source radiating laser light, a control part controlling the output of the laser light source are provided, and the control part is constituted so as to change the output of the laser light source at specified time interval. In a laser light scanning apparatus provided with a laser light source radiating laser light, a control part controlling the output of the laser light source, and a scanning means deflecting the laser light at a specified period, the control part is constituted so as to change an output of the laser light source (S22) when a scanning line is changed over (S21). |
